extract certain keys and values from change

I am using the below in a scripted field

changeHistoryManager.getChangeItemsForField(issue, "status")

which is returning the below :

[com.atlassian.jira.issue.history.ChangeItemBean@4cbf004a[fieldType=jira,field=status,from=10002,fromString=In Development,to=10009,toString=Blocked,created=2021-06-12 01:06:52.792], com.atlassian.jira.issue.history.ChangeItemBean@1c19d69c[fieldType=jira,field=status,from=10009,fromString=Blocked,to=10184,toString=In Design,created=2021-06-12 01:07:05.427], com.atlassian.jira.issue.history.ChangeItemBean@785e386e[fieldType=jira,field=status,from=10002,fromString=In Development,to=10009,toString=Blocked,created=2021-06-12 01:35:41.529], com.atlassian.jira.issue.history.ChangeItemBean@4ee968a0[fieldType=jira,field=status,from=10009,fromString=Blocked,to=10008,toString=Done,created=2021-06-12 01:36:08.516], com.atlassian.jira.issue.history.ChangeItemBean@7a608c67[fieldType=jira,field=status,from=10008,fromString=Done,to=10021,toString=Cancelled,created=2021-06-12 01:37:32.262], com.atlassian.jira.issue.history.ChangeItemBean@289f1881[fieldType=jira,field=status,from=10002,fromString=In Development,to=10009,toString=Blocked,created=2021-06-12 01:42:44.575], com.atlassian.jira.issue.history.ChangeItemBean@218bc8b4[fieldType=jira,field=status,from=10009,fromString=Blocked,to=10184,toString=In Design,created=2021-06-12 01:43:02.087], com.atlassian.jira.issue.history.ChangeItemBean@2422184d[fieldType=jira,field=status,from=19123,fromString=Requires Design,to=10184,toString=In Design,created=2021-06-12 01:56:11.607], com.atlassian.jira.issue.history.ChangeItemBean@5a5fbb1a[fieldType=jira,field=status,from=10002,fromString=In Development,to=10009,toString=Blocked,created=2021-06-12 02:04:08.493]]

I need to know how I can extract only the fromString and toString and their values and save them in a list/map in the same order they appear above.

the list I mean is like for example :

[[fromString=In Development, toString=Blocked ] , [fromString=Blocked, toString=Cancelled ] ]

You can use following snippet to return a List<Map>:

changeHistoryManager.getChangeItemsForField(issue, "status").collect {
  [
    "fromString": it.fromString,
    "toString": it.toString
  ]
}

thank you! @Max Lim _ScriptRunner_

one more question :

how can I remove consecutive duplicate values that fit this condition and only keep one of them :

keep any transition that has In Development and remove the duplicates in the transitions where from and to are anything else other than In Development

so for example here is the list :

[[fromString:Ready for Dev, toString:In Development], [fromString:In Development, toString:Blocked], [fromString:Blocked, toString:In Design], [fromString:In Design, toString:Requires Design]]

and after removing the duplicates that fit the condition :

[[fromString:Ready for Dev, toString:In Development], [fromString:In Development, toString:Blocked], [fromString:In Design, toString:Requires Design]]

Max Lim _ScriptRunner_

Are you saying you only want values with "in Development" in "fromString" and "toString" keys?

You can do this:

changeHistoryManager.getChangeItemsForField(issue, "status").collect {
  [
    "fromString": it.fromString,
    "toString": it.toString
  ]
}.findAll {it.fromString == "In Development" || it.toString == "In Development"}

No not find , I mean something like unique values of from and to together based on a condition like :

( it.toString != "In Development" ) && (it.fromString != "In Development" && it.toString != "Backlog" && it.toString != "Ready for Dev" )

so for example in this list :

[[fromString:Ready for Dev, toString:In Development], [fromString:In Development, toString:Blocked], [fromString:Blocked, toString:In Design], [fromString:In Design, toString:Requires Design]]

we have 2 consecutive elements that fit the condition which are :

[fromString:Blocked, toString:In Design], [fromString:In Design, toString:Requires Design]

so unique should return one of so in the end, it look like that :

[[fromString:Ready for Dev, toString:In Development], [fromString:In Development, toString:Blocked], [fromString:In Design, toString:Requires Design]]
